Host ranges are commonly quantified to classify herbivores and plant pathogens as either
generalists or specialists. Here, we summarize patterns and mechanisms in the interactions …

Thorough pre-release studies to determine the environmental safety of biocontrol agents
and to predict their effectiveness in controlling the target weed are crucial parts of any weed …

Plants and their associated insect herbivores, represent more than 50% of all known species
on earth. The first step in understanding the mechanisms generating and maintaining this …

The long-standing view in ecology is that disparity in overall resource selection is the basis
for identifying niche breadth patterns, with species having narrow selection being classified …

Nestedness and modularity have been recurrently observed in species interaction networks.
Some studies argue that those topologies result from selection against unstable networks …

Insect herbivores are relatively specialized. Why this is so is not clear. We examine
assumptions about associations between local abundance and dietary specialization using …

Tropical ectotherms are particularly vulnerable to global warming because their
physiologies are assumed to be adapted to narrow temperature ranges. This study explores …

Root hemiparasitic plants act as keystone species influencing plant community composition
through their differential suppression of host species. Their own performance also strongly …

One of the best‐known biogeographic rules for ectotherms is the temperature‐size rule,
which asserts that ectotherms produce smaller adults at warmer temperatures. Although this …

Oligophagous herbivores must adjust their enzymatic machinery to the different host plant
species they consume. If different hosts are used from one generation to the next, adaptation …
